While the 360 revolution is upon us I noticed an absence of attention towards the “unimportant” ethernet connection between music server and player.

Now this cable may not carry a lot or any signal while playing, it is a medium that can pick up and conduct undesirable electromagnetic signals. Hence my conjecture that the benefits or effects of the 360 shielding trick might very well apply to the ethernet cables as well.

I do not have the stuff or time to pull such an experiment off. Has anyone done experiments with different ethernet cables and or shielding (like connecting an SFTP shield one way only)?

The only experience I have is that the Ethist^2 can most probably be ordered from of tomorrow because then we will have a picture for the webshop.Otherwise it is that today we all had a day off or else it would have been ready right now.Price can be thought of the same as for the Lush^2 for the shorter lengths; at which lengths it will be available depends a bit on how things work out tomorrow but hopefully long also and then at not crazy prices.

Over here (Phasure) we do not have any experience with it and the Ethist^2 has been made because people request it. A bit of the same as how it went with Blaxius^2 and in the end for sure also how Lush^2 emerged; I reject a couple of times until I start to see that maybe things may work.So an Ethernet cable ? be my guest !

From Ethist^2 via Ethernist^2, we named her ET^2. More tentacles than ever.

So no, it was not so easy at all. This is because when we apply shielding as such, the shielding must also try to be effective. And this does not happen much by wrapping a screen around a able (and an other and an other).

The above can be combined with the sheer fact that Ethernet (or the cable, never mind it is used for Ethernet or is "abused" for outboard i2s connection) officially does not carry a shield which connects to the (plastic) connectors and from there to the device chassis. But this one now does !So technically we made it a completely different beast.

The white (cotton sleeved wires) you see in the photo are the "end to end" connections for the chassis grounding. Thus, envision that the eyes / washers at the end are screwed to the chassis of e.g. a network streaming device for the A (source) side of the cable. And the other (B) end is connected to ...Nothing !We feel that a shield to be effective it should be (or can be) connected to one side (device) only. But is it then not allowed to connect it to both devices ?

That depends ...

If the connection is to provide an Ethernet connection, then it shouldn't connect the two devices in involved, because Ethernet is inherently galvanically isolating. This is for a reason of course, so I'd respect that.

If the connection is meant for i2s, then the application normally requires device to device grounding connection. But wait, this is ground, which is not per sé the chassis. This depends really on what the manufacturers wanted to make of that (but my own idea of : not much thought of, but alas). Now when you'd formally connect the devices by this extra wire (which is what you could always have done) then at least what you prevent is the current of the two devices (ground) potential difference flowing over the data wires (the ground return wires of them).Aha ...And meanwhile, that connection is shielding, just like USB was designed. But also : like with USB it is perfectly allowed to connect the screen/shield to one side (device) only; the shielding will be as effective, but in a different fashion (which, as we now now by definitely sure, makes a quite outrageous audible difference - see the Lush^2).

And so the ET^2 is almost more vigorous than the Lush^2; It undoubtedly improves the connection as such because it adds a dimension. And, if you use the ET^2 for normal Ethernet, then nothing wil break really if you use the ground connection at both ends. It is only that Ethernet was not designed for that, and that by guarantee you will break the galvanic isolation Ethernet had in mind.

So all is up to you.

Of course you understood that the Black wire(s) which normally connect to the ground in - or chassis of the connector(s), now connect to the cotton-sleeved ground wires. Thus, it would be perfectly allowed to connect each of these wires to the respective devices, but decide later which to connect for real by means of applying the respective Black wire to the bridge connector (the connector with the red dot you see in the photo(s)). And of course you again caught that the shield (or shields) to use for the device-device (half) connection, is completely up to you.

While those connection-eyes are for the mere permanent connection, in the package you will also find a pair of crocodile wires so you can more easily test what works best for you. Just connect to an eye on one end of the crocodile wire and the other end somewhere to the device.But there's a pitfall : The cotton-sleeved ground wires itself are shielded ! This means that the crocodile wires - which are not shielded - may deteriorate an otherwise good ground connection (it may catch radiation (RFI) easier). So always expect a technical (and with that possibly audible) difference when you tested with a crocodile wire and later make it permanent but screwing the eye to some part of the device.

Questions ? don't hesitate.Peter

PS: For extra fun and possibilities, it would be allowed to connect the ground wires to themselves (and not to a device at all). Of course you could try all the various internal shield connections with it !
